/usr/sbin/sendmail specification proposal

This sounds right to me.
I took a quick look (that lasted several hours) at sendmail, exim,
qmail's sendmail wrapper, smail, and the Netscape sendmail wrapper.
Anyway, here are the /usr/sbin/sendmail options that seem to be
well-supported and at least somewhat useful. Please review it and we
can incorporate it into the LSB utility specification.

NAME
/usr/sbin/sendmail - an electronic mail transport agent
SYNOPSIS
sendmail [flags] [address ...]
DESCRIPTION
This program sends an email message to one or more recipients,
routing the message as necessary. This is not intended as a user
interface routine.
With no flags, sendmail reads its standard input up to an
end-of-file or a line consisting only of a single dot and sends a
copy of the message found there to all of the addresses listed.
It determines the network(s) to use based on the syntax and
contents of the addresses.
If aliasing is supported on the local system, it can be prevented
by preceding the address with a backslash.
OPTIONS
-bm Deliver mail to the recipient addresses. This is the
default mode of operation.
-bp List information about messages currently in the input
mail queue.
-bs Use the SMTP protocol as described in RFC 821. (Read
SMTP commands on standard input and produce SMTP replies
on standard output.)
-F fullname
Explicitly set the full name of the sender for incoming
mail.
-f name
Explicitly set the sender address for incoming mail (the
"from" person).
-i Ignore dots alone on lines by themselves in incoming
messages.
-odb If background delivery is supported, deliver any mail in
background.
-odf Deliver any mail in foreground.
-oee or -ee
These options refer to a BERKENET error processing style
which is not required. If not supported, report errors
in the same manner as -oem.
-oem or -em
Mail errors back to the sender (default).
-oep or -ep
Write errors to the standard error output.
-oeq or -eq
Do not send notification of errors to the sender. This
only works for mail delivered locally.
-oew or -ew
Write errors to the sender's terminal using the write(1)
command, if he is logged in. Otherwise, mail errors back
to the sender. If not supported, report errors in the
same manner as -oem.
-oi Same as -i.
-om This option means 'me too', indicating that the sender of
a message should receive a copy of the message if the
sender appears in an alias expansion.
-t Read message for recipients. To:, Cc:, and Bcc: lines will
be scanned for people to send to. The Bcc: line will be
deleted before transmission. Any addresses in the
argument list will be suppressed.
-v Be more verbose.
